Windows 11 users are experiencing issues with the update KB5031455, with some systems not installing the update, others encountering installation problems and some seeing error messages as well as gaming issues if the update does install successfully. 

According to Windows Latest, several users have complained to the site about the Windows 11 update, stating the installation would “run and fail, then reboot, run and fail again.”

Another user commented on problems with gaming performance after the update, saying that the build “broke a few games.” According to the user, some games available from Epic Games Store, such as Fortnite and Horizon Zero Dawn, crashed and refused to start. More comments like these have been left on the Windows Latest site. 

This is not the first time a string of issues has been presented due to preview updates.  KB5030310, a preview update for those using Windows 11 22H2, caused issues with File Explorer that led to buggy behaviour and slower run times.

If you’ve yet to install the KB5031455  update, we recommend you hold off a bit longer until these issues are addressed by Microsoft. But, if you’re feeling brave and want to go ahead anyway, you’ll need to go to Settings, then to Windows Update, and select ‘Check for Updates’. Once your device finds the new optional update, click the ‘Download and install’ button.

It’s worth bearing in mind that Windows Latest has tested the update on its own machines and noted the same problems listed above, so once again, we recommend you proceed with caution if you plan to install the update.
